Touch Screens

Michael McAndrew

A touch screen is a visual display that can detect the presence and the exact location of a touch within the device's screen, although the name refers to human touch, there are other implements you can use to touch the screen with to input data, one of the most common is a stylus that the screen can detect. They are common in games consoles, all-in-one computers, tablets and smart phones. A touch screen allows you to interact directly with what is on the screen rather than by using a peripheral device like a mouse or a keyboard.


The device captures input data in place of a mouse, and is a manual device, as it relies on human input before it can execute anything on the computers display.
